Re: What differential lube to use
I don´t think that your jeep is Quadra Drive, because then it should have the NV247 T-case. Not sure if a Vari-lok would fit in the Dana 35, i think its normally only used in the Dana 44. If your jeep doesn´t have the factory tow package, then there should be no vari-lok in the rear diff. In that case, you would only need the 80W90 fluid, 3 Lts or 6 pts in total. You will also need silicone sealant, to seal the diff covers. Also loosen first the fill plugs on the covers, before loosening the covers and draining the fluid, because sometimes the plugs are rotten in place and can´t be removed. That would not be a good thing to discover when the diff is already empty. The front diff cover can be accessed easily with the jeep on the ground, but for the rear one you have to lift the back of the jeep, to get access to the upper diff cover bolts.
